\ BUILDING-BRICK AND WALL CONSTRUCTION.

Specification of Letters Patent.

Patented July 19, 1921.

Application filed April 19, 1918. Serial No. 229,495.

To all whom it may concern:

Be it known that I, GEORGE A, BILQUE, a citizen of the United States, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Building-Bricks and Wall Construction, of which improvement the following is a specification.

My invention relates to improvements in tile bricks and hollow walls constructed therefrom.

The object of my invention is to produce a tile brick having the adaptability, flexibility and stability of the ordinary brick in the construction of walls, with the additional advantage of producing a hollow, moistureproof wall therewith. To accomplish this purpose, the tile brick comprises two separable units and is so constructed and propor tioned that as an entirety it can be used in straight course construction and can be readily severed without waste to form corners and also to form pilasters and openings -in walls, without using any other element than the tile itself, and with which, in wall construction, the continuity of the mortar joints are absolutel maintained. My improved tile brick is, or all practical purposes a complete substitute for the ordinary brick, being brick size in length and twice the width of the ordinary brick. Walls can be constructed therewith more quickly and with less expenditure of labor and mortar than is now necessary in the construction of a hollow or solid wall.

The said invention is more specifically described with reference to the drawings forming part hereof, in which:

1 ure 1 is a perspective of a portion of a wa l constructed in accordance with said invention.

Fig. 2 is a sectional plan of my improved tile brick.

Fig. 3 is a side elevation of the same. Fig. 4 is a vertical central section. Referring to said drawings and describing said tile brick, A is a fiat, substantially square ends of the tile, and by the centrally disposed parallel webs 5 and 6. The said webs, 3 and 4, form respectively the outer walls of the open1ngs, 7 and 8, the inner walls of whlch respectively are formed by the webs, 5 and 6. The said webs, 5 and 6, also form the walls of the centrally disposed opening, 9, and also serve as a hand grip, for handling or laying said tile. The front section, 1, and the rear section, 2, are in effect and function two independent, but connected piers or plllars for the reception of mortar, to form the bond between various courses of t1le in the construction of a wall therefrom. When said tile are laid in courses in wall formation, as shown in Fig. 1, vertically disposed air channels are formed by the openings, 7 8 and 9, and interrupted or non-continuous mortar joints are formed, thus producing a moisture proof wall, in which the.

corners are formed by severing the tile at the notches, a, and usin one-half the tile for this purpose as hea ers or quoins, 10, as shown in Fig. l, at the same time the continuity of the mortar courses is absolutel maintained. The sections 1 and 2 are eacii provided with vertically disposed openings, 11, which are primarily for the purpose of lightening the tile and also for producing substantial uniformity of crop sectional areas therein, thus insuring more uniformity of results in the burning operation. These openings, 11, also serve as receptacles for mortar to form the bond between the tile.

The tile is so proportioned that it canbe used in the same manner that any brick may be used, whether of the ordinary size or any special size; that is to say, it can be used in straight wall construction and in turning corners thereof, as shown in Fig. 1. Pilasters and openings in walls may also be formed without using any other unit than the tile brick itself; that is, without using an ordinary brick or piece thereof, or any specially provided unit.

In said Fig. 1 is shown a sectionof wall constructed with my improved tile. A suitable foundation having been first prepared, the first course of tile is laid='end to end and built up in the usual manner with mortar courses and mortar joints until the corners of said wall are encountered. When a corner is to be constructed or turned, one of the tiles is broken or severed at the notches, (1, thus forming, when ordinary brick sized tile is used, two single units, each of which is about equal in area to the ordinary brick. By

presenting the longitudinal face of one of these units in the face of the wall and one of the finished ends at the section of wall at right angles thereto, as shown in Fig. 1, the corner is turned or produced and the continuity of the joint maintained without employing any other or special unit than the separate part of the tile itself, and without wasting any portion of the tile.

Having described my invention, what I claim and desire to secure by LettersPatent, is:

1. A hollow twin blockstructure comprising two stretcher faces having comparatively wide top surfaces, and two header faces, the said stretcher faces being connected by a plurality of narrow, spacedapart, transverse, vertically disposed, parallel webs and constituting mortar receiving surfaces, the outer of said webs with the end portions of said stretcher faces constituting the header faces, and the centrally disposed, parallel webs being adapted to furnish a hand-hold, the said webs cooperating with said stretcher faces to form the walls of vertically disposed openings in the block, each of said stretcher faces and header faces being equal in length, width and thickness to the corresponding parts of a building brick.

2. A hollow twin brick structure having two stretcher faces and two header faces, all of said faces having substantially the same dimensions, one of said header faces being provided with a centrally located channelshaped recess adapted to divide said face into two similar header portions, the sides of said channel-shaped recess intersecting the header face at substantially right angles to form uare corners on each of said header portions, and a portion of the inner wall of said recess being formed at substantially right angles to the saidfside walls thereof to give a definite depth to the recess, said recess also forming a cleavage portion facilitating the breaking of the twin brick structure into two similar standard sized bricks each having a finished stretcher face and a finished header end, and partition walls within the body of the brick on opposite sides of said channel-shaped recess and offset therefrom, said walls extending substantially parallel to said stretcher faces, substantially as described.

3. A hollow twin block structure comprising two stretcher faces, each of which is provided with a wide top surface, and two header faces, the said stretcher faces being connected by a plurality of narrow, spaced apart, transverse, vertically disposed parallel webs, the said wide surfaces furnishing mortar receiving surfaces, the outer of said webs with the end portion of said stretcher faces constituting the header faces, the said webs cooperating with said stretcher faces to form walls of vertically disposed openings in the block, and each of the wide surfaces of said stretcher faces being provided with vertically disposed openings which form mortar keys, and with said narrow connecting webs furnish means for lightening said block.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
